I agree. I don't even think there was an emotional conversation that night. He's too sneaky and non-confrontational. I think even if she did try to talk about it, he put her off. "It's too late, just get some rest (or "I'm way too tired right now for that crap), we'll talk tomorrow". Then after she had drifted off as she laid on her left side, he climbed on top of her, pinning her arms under the blankets, and strangled her, primarily grasping her neck on her right side, cutting off the blood flow, which leads to loss of consciousness within seconds. She didn't have a fighting chance.
